GeForce.com now offers new NVIDIA GeForce beta version 301.24 drivers, adding new gaming features and promising a performance boost in The Elder Scrolls V: Skyrim. Here's a bit on what the new driver family introduces:

With the release of the GeForce 301.24 beta driver, a high-speed, shader-based anti-aliasing technique can be applied directly to hundreds of games through the NVIDIA Control Panel. Called NVIDIA FXAA, this technique is up to 60% faster than 4xMSAA, and can produce results equal to or better than the ageing anti-aliasing solution. Furthermore, FXAA is able to anti-alias increasingly-popular transparent textures, as shown in our Batman: Arkham City Graphics Breakdown and Performance Guide, making it the clear winner in many of today’s games.

I've been using onboard audio recently, it does the job but there is a lot of hiss. However, I couldn't be bothered with the hassle the Creative tend to put me through. Is something like a Xonar any good?
